    • Solid G-Shock with Great Features
Had this for a week and very impressed. Bluetooth connects perfectly to my Iphone, solar charging keeps it powered without issues, and the build quality is excellent as expected from G-Shock. Surprisingly comfortable for daily wear despite the rugged design. The black look is clean and versatile. Highly recommend! ... show more

    • Mechanical watch guy is impressed.
I am a mechanic watch guy, but I have a love for watches in general. This watch was purchased for hard use situations, and it is typically worn on the water. It lives in a dark drawer and when I remove it the hands spring to life and automatically adjust to the correct time, I love that. I also really like the phone connectivity, which saves me from having to stumble with the buttons and ensures accuracy. I don't wear it very often. So, the fact that it hibernates while not in use is great as far as it's life span is concerned. The solar charging is also a great feature. Overall, just a real slick watch. ... show more

    • Great watch, easy to customize and fits good. Gshock for the win !
Great watch, heavy duty and ease of use. The light is nice and bright at night and time keeping or time retention is perfect due to the phone connection. Definitely great value watch and the custom upgrades are endless if you want to make Casioak. Only think what need work is the app Casio has. That think is like one big commercial and the phone battery drain is BAD. I will be using the watch without the app till better version gets released. ... show more

    • Fantastic watch!
As described, used but like new with some damage to the packaging. I love the bluetooth/solar G Shocks, so I was happy to save a few bucks on this one.

    • Doesn’t keep time
Have owned Casio watches before and liked them. I also like this watch. That said- Casio quality has obviously taken a nose dive. I charged this watch fully then sync it to my iPhone/ Casio app numerous times per day- even with this, it falls 9-11 minutes behind every 8 hours. It also feels like a cheap plastic toy. Returned- no more Casio for me. ... show more

    • Not authorized retailers (read for details)
I received a genuine GSHOCK watch. I wasn't sure at first as the packaging was not the same as I had seen elsewhere but had Casio confirm it was authentic. Connected to the app no problem, keeps time and updates itself through the day. What's much smaller than I expected, which was my biggest fear having fairly small wrists. So far absolutely no complaints. BUT NOTE FOR THOSE BUYING FROM AMAZON: A lot of the sellers on Amazon are not authorized retailers for Casio and you will not be able to activate/use the 1 year warranty on the product. ... show more
